• Electrical Equipment

WARNING! Electrical controls shall be installed and wired by a qualified electrician.
Wiring information for the motor and controls are furnished by the equipment manu-
CONTROLS
Electrical Code: All motor controls and wiring shall conform to the National
Electrical Code (Article 670 or other applicable articles) as published by
the National Fire Protection Association and as approved by the American
Standards Institute, Inc.
CONTROL STATIONS
A) Control stations should be so arranged and located that the operation of
the equipment is visible from them, and shall be clearly marked or labeled to
indicate the function controlled.
B) A conveyor which would cause injury when started shall not be started
until employees in the area are alerted by a signal or by a designated person
that the conveyor is about to start.
When a conveyor would cause injury when started and is automatically
controlled or must be controlled from a remote location, an audible device
shall be provided which can be clearly heard at all points along the conveyor
where personnel may be present. The warning device shall be actuated by
the controller device starting the conveyor and shall continue for a required
period of time before the conveyor starts. A flashing light or similar visual
warning may be used in conjunction with or in place of the audible device if
more effective in particular circumstances.
Where system function would be seriously hindered or adversely affected
by the required time delay or where the intent of the warning may be misinter-
preted (i.e., a work area with many different conveyors and allied devices),
clear, concise, and legible warning shall be provided. The warning shall
indicate that conveyors and allied equipment may be started at any time, that
danger exists, and that personnel must keep clear. The warnings shall be
provided along the conveyor at areas not guarded by position or location.
C) Remotely and automatically controlled conveyors, and conveyors where
operator stations are not manned or are beyond voice and visual contact from
drive areas, loading areas, transfer points, and other potentially hazardous
locations on the conveyor path not guarded by location, position, or guards,
shall be furnished with emergency stop buttons, pull cords, limit switches, or
similar emergency stop devices.
All such emergency stop devices shall be easily identifiable in the imme-
diate vicinity of such locations unless guarded by location, position, or guards.
Where the design, function, and operation of such conveyor clearly is not
hazardous to personnel, an emergency stop device is not required.
The emergency stop device shall act directly on the control of the con-
veyor concerned and shall not depend on the stopping of any other equip-
ment. The emergency stop devices shall be installed so that they cannot be
overridden from other locations.
d) Inactive and unused actuators, controllers, and wiring should be removed
from control stations and panel boards, together with obsolete diagrams, indi-
cators, control labels, and other material which serve to confuse the opera-
tor.
SAFETY dEVICES
A) All safety devices, including wiring of electrical safety devices, shall be
arranged to operate in a "Fail-Safe" manner, that is, if power failure or failure
of the device itself would occur, a hazardous condition must not result.
B) Emergency Stops and Restarts. Conveyor controls shall be so arranged
that, in case of emergency stop, manual reset or start at the location where
the emergency stop was initiated, shall be required of the conveyor(s) and
associated equipment to resume operation.
C) Before restarting a conveyor which has been stopped because of an
emergency, an inspection of the conveyor shall be made and the cause of
the stoppage determined. The starting device shall be locked out before any
attempt is made to remove the cause of stoppage, unless operation is neces-
sary to determine the cause or to safely remove the stoppage.
Refer to ANSI z244.1-1982, American National Standard for Personnel
Protection – Lockout/Tagout of Energy Sources – minimum Safety
Requirements and OSHA Standard Number 29 CFR 1910.147 "The Control
of Hazardous Energy (Lockout/Tagout)."

OPERATION

• Conveyor Start-Up

Before conveyor is turned on, check for foreign objects that may have been
left inside conveyor during installation. These objects could cause serious
damage during start-up. After conveyor has been turned on and is operating,
check motors, reducers, and moving parts to make sure they are working
freely.
CAUTION! Because of the many moving parts on the conveyor, all personnel in the
area of the conveyor need to be warned that the conveyor is about to be started.
MAINTENANCE

• Lubrication

The drive chain is pre-lubricated from the manufacturer by a hot dipping
process that ensures total lubrication of all components. However, continued
proper lubrication will greatly extend the useful life of every drive chain.
drive Chain lubrication serves several purposes including:
• Protecting against wear of the pin-bushing joint
• Lubricating chain-sprocket contact surfaces
• Preventing rust or corrosion
For normal operating environments, lubricate every 2080 hours of operation
or every 6 months, whichever comes first. Lubricate with a good grade of
petroleum or synthetic oil (i.e., Shell Rotella or mobil 1). For best results,
always use a brush to generously lubricate the chain. The proper viscos-
ity of lubricant greatly affects its ability to flow into the internal areas of the
chain. Refer to the table below for the proper viscosity of lubricant for your
application.

The drive chain's lubrication requirement is greatly affected by the operating
conditions. For harsh conditions such as damp environments, dusty environ-
ments, excessive speeds, or elevated temperatures, it is best to lubricate
more frequently. It may be best, under these conditions, to develop a custom
lubrication schedule for your specific application. A custom lubrication sched-
ule may be developed by inspecting the drive chain on regular time intervals
for sufficient lubrication. Once the time interval is determined at which the
chain is not sufficiently lubricated, lubricate it and schedule the future lubrica-
tion intervals accordingly.

• Belt Installation

INSTALLING THE BELT
The conveyor drive belt has been pre-cut and the proper lacing attached at
the factory. Thread belt through conveyor per Figure 6B. Note that there
should be no air pressure on the pneumatic tensioner (if supplied). Pull belt
ends together and insert lacing pin. (Figure 6A). Adjust take-up to remove
slack from the belt.
NOTE: If belt ends cannot be pulled together by hand, it may be necessary to loosen
take-up pulley (in drive) to minimum position or use a belt puller so lacing pin can be
easily inserted.
BELT TENSION
For maximum efficiency, maintain enough belt tension so drive pulley will
not slip when carrying the rated load. Belt tension should be adjusted with
the take-up pulley in the drive. (Figure 7) Keep pulley square with bed by
moving both take-up bolts an equal amount.
Pneumatic Tensioner (when supplied):
Initial Tension:
With no air pressure on tensioner, take up the belt until the unit runs and
the drive pulley does not slip (keeping pulley square). With unit turned
off, back the jam nuts off by a distance of 1/2". Lock jam nuts at this loca-
tion. Starting at 10 psi, increase air pressure until the tensioner strokes
1/2" (measure gap between channel and UHmW block). Tensioner will now
have 2" of additional stroke and 1/2" of relief.
Resetting Tension:
When the tensioner approaches full stroke the take-up should be adjusted
until the tensioner is set at 1/2" again.
